Echinacea purpurea plant named &#39;little giant&#39;

ABSTRACT

A new and distinct cultivar of  Echinacea purpurea  plant named ‘Little Giant’ characterized by its unique flowers with numerous red purple rays that radiate out, orange cone, lovely fragrance, and an upright dwarf habit.

BOTANICAL CLASSIFICATION

Echinacea purpurea

VARIETY DESIGNATION

‘Little Giant’

The present invention relates to a new and distinct cultivar of Echinacea purpurea and given the cultivar name ‘Little Giant’. Echinacea is in the family Asteraceae. This new cultivar originated as a whole plant mutation in a mass planting of Echinacea purpurea ‘Ruby Giant’ (an unpatented plant) in the nursery trial fields in Canby, Oreg.

This new Echinacea purpurea cultivar is distinguished by:

-   -   1. Large red purple flowers with a double row of ray flowers.     -   2. Dwarf habit.     -   3. Lovely fragrance.     -   4. Ray flowers which spread out parallel to ground, slightly         ruffled.     -   5. Strong upright stems.     -   6. Good vigor.

This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with changes in the environment without a change in the genotype of the plant.

COMPARISONS TO SIMILAR ECHINACEA

Compared to Echinacea purpurea ‘Ruby Giant’, an unpatented plant and the parent, the new cultivar is much shorter with longer thinner leaves. The flowers of the new cultivar are a deeper red purple in color.

Compared to Echinacea purpurea ‘Kim's Knee-Hi’ (U.S. Plant Pat. No. 12,242), the new cultivar is shorter with wider flower heads that stiffly radiate rather than rigidly reflex and are colored deep red purple rather than rosy pink to purple pink. The new cultivar also has more ray flowers.
